To all whom t may concern:

Be it known that I, WILLIAM FRANKLIN LAws, a citizen ofthe UnitedStates, residing at Governors Island, in the county of Swain and Stateof North Carolina, have invented certain new and useful Improvements inT-ethers, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to tethers, and more particularly to that classknown as Htravelers, onel of the` objects being to provide simple andinexpensive means for tethering or picketing an animal for the purposeof grazing and the like, so that it may traverse a considerable areawithout danger of becoming entangled in the tethering-rope.

Other objects and advantages of my invention, as well as the structuralfeatures by means of which these objects are attained, will be madeclear by an examination of the specification, taken in connection withthe accompanying drawings, in which the same reference-numerals indicatecorresponding portions throughout, and in Which- Figure 1 is aperspective view of my complete device, showing one end of thetetheringrope connected with a cow 5 and Fig. 2 is a detail of parts. l

1 designates vertical standards or uprights, having their lower endsfirmly embedded in the earth, so as to be held securely in position.Stretched between the standards is a rope or cable 2, along which is adated to travel a pulley 3, from which depen s a ball and socket 4, havingsuspended therefrom the pulleys 5 and,6. Secured to the pulley 5 is thetethering-rope 7, which supports the pulley 6, and from said pulley 6 aweight 8 is suspended, said pulleys 5 and 6 andthe tethering-rope 7Jforming, in effect, a block-andtackle arrangement. The weight 8 is onlysuliciently large to keep the rope 7 taut and may be varied according tothe strength or size of the animal tethered. In order that said animalmay not pass around the uprights 1, and thus become fastened in anymanner or its movementslimited thereby, I provide the blocks 9, whichare provided with a longitudinal groove 10, through which the rope orcable 2 extends, and also with set or thumb screws 1 1, whereby saidblocks maybe tightened to grip the rope or cable 2 in such manner as tobe held securely'in position. As the pulley 3 travels along said rope orcable in either direction it comes in contact with one of said blocks 9and is stopped thereby, so that the extent of the travel of the pulley 3is limited according to the points at which said blocks are secured onsaid rope r`2. As the animal moves about over the ground theball-and-socket arrangement 4 admits ofthe rotation of the pulleys 5 and6. Consequently the rope 7, leading from the neck of the animal, cannotbecome entangled in the arrangement of parts held suspended from therope or cable 2.'

The construction and operation of this device, it is believed, will beobvious from the foregoing description, and further explanation is notdeemed necessary.

Having thus described my said invention, what I claim as new, and desireto secure by Letters Patent of the United States, is-

1. In a device of the character described, vertical uprights, a cablestretched between said uprights and held suspended thereby, a

pulley adapted to travel along said cable, a plurality of blocks eachhaving a longitudinal groove therein to span the cable, setscrewsarranged in the blocks and adapted to bring the edges on each side ofthe groove closer together to grip the cable and thereby hold the blocksin adjusted position, and to release the edges to permit of adjustmentof the blocks longitudinal of the cable, the blocks being adapted tolimit the travel of the pulley, a second pulley, a ball-and-socketconnection between said pulleys, a tetheringrope having one enddepending from the second-mentioned pulley and the other end passingo'ver it and thence t\ the animal whereby said animal is tethered, and aweighted pulley engaging the tethering-rope whereby the same is heldtaut against the movements of the animal.

2. Adevice of the character described coml movement of said pulleys withrespect to 11o IOO each other and having a loose or link oonneotially asdescribed and `for the purpose set forth.

In testimony whereof I hereunto afHX signature in presence of tWoWitnesses.
